No one said anything about the numbers or the value of a victim, only that society doesn't allow a man to be a victim, at least, not to a woman, and not without ridicule, guilt, and other "fun" stuff.
It doesn't take away from the overwhelming number of female victims, not at all.
But the fact remains that for every reported case of domestic abuse between heterosexual partners where the man is the victim, we have no way of knowing how many go unreported and unspoken. Even in those cases where the abuse is reported the man may argue that he's no victim and so the case never goes beyond the report.
If a woman goes to her family saying "my husband hit me" (in the western world/culture) she is encouraged to leave him and given all the help and support she needs.
If a man goes to his family and says "my wife hit me" he's likely to be laughed at, told to man up, and have his masculinity attacked.
The numbers of reported cases tell us that women are far more often abused than men, but that doesn't mean that domestic violence = "violence against women" only.
